Calculating the Output

Geometry Expressions will make calculations in the geometry based on any constraints or constructions you have specified, or just from the sketch. Calculations can be output in Real or Symbolic terms by choosing the appropriate tab.

If you haven't supplied all of the necessary input constraints, the system inserts any missing variables automatically or, for real calculations, bases the value on the sketch.

Some calculations may take longer than you expected. If the calculation isn't immediate, you can stop it and restart it with these buttons on the tool bar.

ebd_Ebd187  Stop calculations

ebd_Ebd188  Start calculations.

You may want to reconsider the problem, add constraints, or just let it continue with the calculation.

The Stop calculations and Start calculations can also be found under Calculate (Output) menu and under the general context menu.

The table below lists all the available calculations and geometry elements which must be preselected. Be careful when selecting geometry objects, if extra things are selected that are not related to the calculation (like other calculations) the calculations will remain inactive. This can happen by mistake, especially when using the selection rectangle.
